Hmm, I think they do. Can you point to one parser that is not 
reusable? Should we take this up with the SAX folks? In fact, never 
miond. They already say this, and I quote from 
http://www.saxproject.org/apidoc/org/xml/sax/XMLReader.html#parse(org.xml.sax.InputSource):

Applications may not invoke this method while a parse is in progress 
(they should create a new XMLReader instead for each nested XML 
document). Once a parse is complete, an application may reuse the 
same XMLReader object, possibly with a different input source.

Any XML parser that does not allow reuse is not conformant with the 
SAX specification. I think we're reasonably safe in relying on parser 
reuse, and there's no need to clutter the API with an additional 
method to turn parser reuse on and off.
